Hi Andrew,

you may want to implement a lookup table populated with the stopwords and only stem a word in input if it is not in the stopwords table.

It should be quite easy to implement in Java, but let me know if you need assistance.

Have a nice day, 
    Oerd

Hi Olly

I imagine removing stop words is a fairly common requirement. Any idea how people implement stop word removal with  snowball? 

The reason I originally thought snowball provided stop word removal was because of the following links  http://snowball.tartarus.org/algorithms/english/stop.txt (from http://snowball.tartarus.org/algorithms/english/stemmer.html)

It seems to suggest there is some stop word support

Thanks

Andy

today I downloaded the java version of snowball and compiled it. I ran
a couple of little example through it. It does not appear to remove
stop works. Is this a bug? 

That's not a bug - snowball is a stemmer, not a stopword remover.

Cheers,
   Olly
